I have never heard of Vimulti, but the product I've been using is called SoloSlim. I love it!!! (oh god, I sound like an infommercial...lol!) But seriously, I have been using it since June 2009 and I've lost 16 lbs. It only has 8 ingredients, is all natural AND you only take one per day. I love that, cuz I'm forgetful. I have tried everything out there, and this has been the ONLY thing that has EVER worked. I ordered the Extra strength first, considering my bodies resistance to weightloss. Side effects? The only thing is it makes you REALLY thirsty, I mean, your mouth is like the Sahara desert!! Water is good for weightloss though right?! I'm not very hungry throughout the day, when I am, I seem to only want something healthy (I am on a diet right?) Not saying that I haven't had icecream for dinner, 5 days in a row. (1 scoop only) I also starting taking probiotics for my stomach. They're good for everyone. Get the best ones, in the refridgerator case. And B12 (Im deficient, due to low enzymes, hence the probiotics) I take sublingual and tablets. I hope this is of help to you. Good luck in your weightloss efforts!! (soloslim dot com) PS I am a normal person, honest!!
